NOTE: The system is powered-up as soon as you connect the power cord between the system
and the power source.
CAUTION: Always disconnect the power cable before you service the power supply slots.
CAUTION: Use the power supply cord as the main disconnect device on the AC system.
Ensure that the socket-outlet is located/installed near the equipment and is easily accessible.
4. Repeat steps 1 through 3 above using the second PSU.
NOTE: Ensure that the PSU is correctly installed. When you correctly install the PSU, the power

Assembling and Connecting the Safety Ground Wire for
DC Power Supply
WARNING: For equipment using –(48–60) V DC power supplies, a qualified electrician must
perform all connections to DC power and to safety grounds. Do not attempt connecting to DC
power or installing grounds yourself. All electrical wiring must comply with applicable local or
national codes and practices. Damage due to servicing that Dell Networking did not authorize is
not covered by your warranty.
1. Strip the insulation from the end of the green/yellow wire, exposing approximately 4.5 mm (0.175
inch) of copper wire.
2. Using a hand-crimping tool (Tyco Electronics, 58433-3 or equivalent), crimp the ring-tongue
terminal (Jeeson Terminals Inc., R5-4SA or equivalent) to the green/yellow wire (safety ground wire).
3. Connect the safety ground wire to the grounding post on the back of the system using a #6–32 nut
equipped with a locking washer.
